I am not arguing for corruption, I am just saying that corruption appears for certain reasons, and can be the least painful mean to motivate individuals and raise a system out of its mediocrity. I don't really think it's a good thing, it's just a social phenomena.

The war on drugs is born out of the fear of citizens not being able to regulate their consumption of narcotics, just like during the prohibition.

If you remove your moral compass, you quickly understand a lot of how the human world works.

Corruption is a form of currency, and always has been. It is the norm. It makes thing much easier for a leadership system to work fast within a tight loop of trusted insiders. It is evil, but at the end of the day it reflects the will of voters if they don't try hard enough to stop it.
